1. Gather the necessary materials. You will need a recorder, a music stand (or a flat surface to place the music), and the sheet music for "London's Burning."
2. Hold the recorder correctly. The recorder should be held in your right hand, with the index finger and thumb on top and the middle, ring, and pinky fingers underneath. The left hand should be placed at the bottom of the recorder, with the thumb on the back and the fingers covering the holes in the front.
3. Prepare your recorder. Blow gently into the mouthpiece of the recorder to make sure it is not blocked. If it is blocked, you can use a pipe cleaner or a thin wire to clear the blockage.
4. Play the first note. The first note of "London's Burning" is the note E. To play the note E, place the index finger and middle finger of your left hand over the two top holes of the recorder. Blow gently into the mouthpiece until you hear the note E.
5. Continue playing the notes. Continue to play the notes of "London's Burning" according to the sheet music. The notes are: E, E, G, G, A, A, G.
6. Repeat. Once you have played the entire phrase, repeat it until you have played the whole song.
